Abstract

The invention relates to a sealing means for a mixing-­ delivering piston tap in machines for instant production of so-called "espresso" ice-cream, of the type comprising a cylindrical piston slidingly placed in a seat having a conju­ gate shape and provided with two O-rings which are placed, when the tap is closed, upstream and respectively down­ stream the outlet openings, in said seat, of ducts feeding ice-cream of different tastes from separate ice-cream mixing and producing cylinders, said O-rings being housed in annular grooves lying in planes perpendicular to the piston axis. In order to avoid any passage of ice-cream from one mixing and producing cylinder to the other one through the tap, a third groove is provided on the side wall of said piston, said groove extending along an ellipse defined by a plane intersecting said piston between said O-rings perpendicular to the piston axis, and forming an angle with the piston axis such that, when the piston is in its closed position, each of said outlet openings of ice-cream feeding ducts is completely contained in each one of the half-spaces defined by said plane, said groove being designed to receive a usual, commercially available O-ring.
